Application filed May 13, 1913.

To aZZ whom it may concern:

Be it known that I, FRANK C. Bonn, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Steam-Pressure RegulatorValves, of which the following is a specification.

My invention relates to improvements in steam pressure regulator valvesin which the supply of fuel is regulated by the pressure of steam; andthe objects of my improvement are, first, to provide a *alve by means ofwhich the supply of fuel is regulated by the pressure of steam, andsecond, to provide adjustments by which the supply of fuel may beregulated with different pressures of steam, and third, to provide meansfor automatically controlling the supply of fuel to the steam producingburner. These objects, together with other objects readily apparent tothose skilled in the art, I attain by the construction illustrated inthe accompanying drawings, although my invention may be embodied in avariety ofother me chanical forms, the construction illustrated beingchosen by way of example.

In the accompanying drawing l igure 1 is a side elevation of theregulator and valv Fig. 2 is a longitudinal section. Fig. 3 is adetached view of the fuel or gas regulating needle and its adjustablehead. t is a view showing a portion of the valve illustrating the steamand spring controlled chambers together with the flexible disk or(llilpl'lltlglll dividing sheet chamber. Fig. 5 is a transverse sectionon line 55, Fig. 2.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawing.

In the accompanying drawing, 1 represents the steam chamber casing and 2the spring chamber casing, which casings are connected together by meansof a coupler or union 3, which coupler or union is of the ordinaryconstruction. To the steam Cl121l11- ber casing 1 is attached the steampipe 4, which steam pipe is connected to the radiator or other steamheating device in which steam is generated by a suitable burnerconnected to the body 5, which body is provided with a gas outletaperture 6 or what might be more specifically termed the gas tip of theburner. The body 5 is provided with the valve casing Specification ofLetters Patent.

' T, in which is located the valve 8, which valve is operated by thevalve handle 9.

To the valve casing 7 is attached a fuel or supply pipe by means of theordinary screw threads 10, said supply pipe being connected to anysource of supply such as street pipes properly connected to a gasometeror other source of supply, reference being had to the kind of gasemployed.

lVithin the steam chamber is located the screw threaded bar 11, whichscrew threaded bar is held in fixed adjustment by means of a screwthreaded aperture formed in the end 12 of the steam casing l. in thespring controlled chamber 2 is located the spring 13, which spring islocated around that portion of the needle bar 14-, which is extendedinto the spring chamber. Between the chambers formed by the casings 1and 2 is located the flexible diaphragm 15, which flexible diaphragm isheld in position by means of the flange 16 and the end of the springchamber casing 17 as best illustrated in Fig. 4c. The screw threaded bar11 is for the purpose of limiting the moveu'ient of the diaphragm causedby the action of the spring 1.3 and for the purpose of adjusting thismovement of the diaphragm the screw threaded bar 11 is adjusted to orfrom said diaphragm 15.

The operation of the regulator is substantially as follows: When thesteam pressure becomes below the pressure desired. thereby reducing thedegree of heat. wanted, the spring 13 will move the needle bar Lt towardthe diaphragm 15, thereby moving the needle point 18, away from the tipor aperture 6 and admitting a greater supply of gas to the burner andincreasing the amount of steam and heat, which increased pressure whengreater than desired will move the diaphragm 15 and the needle bar l tin the opposite direction and reduces the supply of gas to the burner,the said movement of the needle bar also contacts the spring 13. It willbe noted that the supply of gas should not be entirely out off by thesteam pressure, but when it is desired to cut off the supply of gas tothe burner the valve 8 is closed by means of the handle 9.

It is well understood that in heating systems, the degree of heatdesired varies from time to time, owing to different degrees oftemperature and during excessive cold weather more heat is required thanis necessary during periods of moderate temperature. In order to providefor the proper regulation of the heat with reference to weatherconditions the adjustable sleeve 19 is provided, which sleeve is locatedupon the needle bar 14, and is provided with the flange 20, which flangeforms an abutment for one end of the spring 13, the opposite end of saidspring abutting against the inner end of the valve casing T.

It will be understood that by adjusting the sleeve 19 in oppositedirections, the tension of the spring will be increased or decreased,reference being had to the adjustment of the sleeve 19, by whichadjustment greater or less steam force is required so that the degree ofheat may be automatically regulated to produce the desired amount ofheat, reference being had to weather conditions as to heat and cold.

For the purpose of providing means for properly inclosing the extendedend of the screw threaded bar 11, the steam chamber casing 1 is providedwith the screw threaded extension 21 upon which is located the cap orcover 22, said cap or cover being for the purpose of giving the va veproper, and neat appearance, and protecting the bar 11.

V For the purpose of providing for the escape of steam from the steamchamber the screw threaded extension 21 is provided with internal screwthreads which are for the purpose of receiving the screw threads formedupon the packing holding sleeve 23, which sleeve is for the purpose ofholding the packing 2%. In order that there may be no stopping of theflow of gas or possible clog ging during the time the valve 8 is open orpartially opened, the needle bar 14: is provided with the angularportion or part 24, the apexes of said angular portion or part 24: beingso arranged that they will come in contact or nearly in contact with thewall of the outlet gas passage 25 located through the burner body 5,thereby producing the gas passage 26.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent, is

1. In a device of the character described, the combination of steam andspring chamber casings, means for connecting said chambers together,said steam chamber provided with a screw threaded extension, the

spring chamber casin provided with a burner tipped body, a gas passagelocated through said body, a valve adapted to regulate the fuel supplyto the burner tip, a needle bar partially located within the springchamber casing and extended into the burner body, an adjustable sleevelocated upon the end of the needle bar located in the spring chamber,said sleeve provided with an outward extended flange, a spring locatedaround the needle bar and adapted to bear against the adjustable sleeve,a screw threaded bar partially located within the steam chamber and inthe screw threaded extension, a diaphragm adapted to be clamped betweenthe spring and steam chamber casings, a packing adapted to press againstone side of the diaphragm, and a packing holding sleeve adjustablyconnected to the screw threaded bar, substantially as and for thepurpose specified.

2. In a device of the character described, the combination of steam andspring chamber casings, means for connecting said chambers together,said steam chamber provided with a screw threaded extension, the springchamber casing provided with a burner tipped body, a gas passage locatedthrough said body, a valve adapted to regulate the fuel supply to theburner tip, a needle bar provided with an angular portion and partiallylocated within the spring chamber casing and extended into the burnerbody, an adjustable sleeve located in the spring chamber, said sleeveprovided with an outward extended flange, a spring located around theneedle bar and adapted to bear against the adjustable sleeve, a screwthreaded bar partially located within the steam chamber and in the screwthreaded extension, a diaphragm adapted to be clamped between the springand steam chamber casings, a packing adapted to press against one sideof the diaphragm, and a packing holding sleeve adjustably connected tothe screw threaded bar, substantially as and for the purpose specified.

In testimony that I claim the above, I have hereunto subscribed my namein the presence of two witnesses.
